And on the exposures we're looking for an eighth of a second, a half a second. And, if you think you can steady the camera against anything to get longer exposures, 2 seconds, 4 seconds, and 8 seconds. Over.

Roger. We'd like to do a little CRYO tank balancing. So, if you could position the oxygen tank number 1 heater switch to OFF and hydrogen tank 2 heater switch to OFF leaving all the rest of the CRYO switches the same, we'll let it run that way for a few hours. Over.

And, Houston, I'd suggest that along the ecliptic line we can see the corona light out to two lunar diameters from this location. The bright light only extends out about an eighth to a quarter of the lunar radius.

Houston, it's been a real change for us. Now we are able to see stars again and recognize constellations for the first time on the trip. It's—the sky is full of stars. Just like the nightside of Earth. But all the way here, we have only been able to see stars occasionally and perhaps through the monocular, but not recognize any star patterns.

All right. On the secondary loop check when we went to FLOW on the secondary radiators, the quantity dropped from 40 percent down to 36 in the first 10 seconds and then stabilized at 36 for the remainder of the 30 seconds.

Apollo 11, this is Houston. We believe that is normal system operation. The radiators are expected to be very cold right now and apparently the decrease you saw was due to contraction in the fluid. Over.
